jesus christ you went full retard.
you wouldn't happen to be 15 years old would you?
but I agree douglas shouldn't be announcing. it's not like he's mistaking rodeos for flatspins here, it's basic math and adding and to be honest I bet a lot of average joe park rats could do a better job than he is at it. 270s are noticeably different from 450s. it's not like he was calling dub cork 12s as dub 16s which honestly look very similar to me.
like said above, he did it 3 times. 3 times can't be mistakes. I don't know how someone could fuck up calling tricks that bad.
